I love new camera releases, certainly brings out interesting responses from people, especially before we have heard from anyone who has actually held the thing, makes me laugh!
Who knows, this could have high ISO performance like the A7s with more resolution, it could play well with other leica lenses, I happen to agree with the above that if it works with exiting lenses then releasing zooms that compliment is a smart idea. It does have a similar form factor to the Sony but that's nothing new, canon's look like nikons, I don't think it's a bad thing.
Anyway, it's just a camera, buy it, don't buy it, the world will still spin!
